Apparatus and method for influencing oscillations in the passenger compartment of a motor vehicle and apparatus and method for detecting defects in a motor vehicle |
摘要 |
An apparatus for modifying noise oscillations in a passenger compartment (12) of a motor vehicle (14) includes a memory device (38) for storing a plurality of predetermined oscillation patterns (SM), an operating condition determination device (18) for determining an operating condition (BZ) of the motor vehicle (14), a selector device (36) for selecting an oscillation pattern (SM) as a function of the determined operating condition (BZ) of the motor vehicle (14), and an oscillation generator device (39-42-44) for generating oscillations corresponding to the selected oscillation pattern (SM) into the passenger compartment (12) of the motor vehicle (14).
